sure, i will take a look at it.
But i'm afraid i cannot continue tracking from next week, i'm under
leaving process at Intel.

At first glance, i saw a lot of errors:

[  772.822663] playback write error (DMA or IRQ trouble?)
[  782.912776] playback write error (DMA or IRQ trouble?)
[  793.002904] playback write error (DMA or IRQ trouble?)
[  803.093052] playback write error (DMA or IRQ trouble?)
[  813.183205] playback write error (DMA or IRQ trouble?)
[  823.273217] playback write error (DMA or IRQ trouble?)

I know this issue on some Haswell ULT boards(STP/WTM1) because they
are not stable, and it's better to use latest BIOS image(V131 or
later).
The log message like below are not critical, in fact they're just
"Warning", it will not harm audio playback:
 [    1.803595] hda_codec: invalid CONNECT_LIST verb 5[1]:0

And seems the proper HDMI device should be pin6, i hope Alexander E.
Patrakov could help check below command at first:
speak-test -t wav -c 2 -D hw:0,7

And pleaset let me know can you reproduce this issue 100% on the same
board? Did you test on some other boards with same Hardware?

thanks
